Extracted text: A reaction of the type A-nR is carried out in gas phase. The reactant A is introduced with an inert I in a batch reaction at constant volume. The initial pressures of the reactant and inert are 7.5 and 1.5 mmHg, respectively. The reaction is irreversible and the total pressure reaches 31.5 mm Hg after a long time. Determine the stoichiometry n and calculate the conversion after 20 min of reaction, knowing that the pressure was 19 mmHg. n = XA =
